Peach tree named ‘GP10’

ABSTRACT

A new and distinct variety of peach tree is characterized by producing a large fruit for commercial harvesting and shipment between September 16-30 in the San Joaquin Valley of Central California. The new variety is somewhat similar to the fruit of ‘Prima Gattie’ (U.S. Plant Pat. No. 10,085) peach tree, but is distinguishable in that it produces fruit 7-10 days after ‘Prima Gattie’ with good blush color, juice production and excellent flavor.

Latin name of the genus and species: The peach cultivar of this invention is botanically identified as Prunus persica.

Variety denomination: The variety denomination is ‘GP10’.

BACKGROUND OF THE INVENTION

Commercially acceptable fruit or peach trees are abundant throughout the growing season. However, those commercial varieties of acceptable fruit of early maturing or late maturing varieties of peach are generally marginally successful because of small size, poor coloration, undesirable flavor, or poor handling characteristics. Those peach varieties that are early or late maturing fruit, but which possess characteristics that are more typical of fruit ripening at the height of the growing season, are of commercial value. This new variety of peach is such a variety of peach tree.

ORIGIN AND ASEXUAL REPRODUCTION

The variety was discovered as a seedling in September 2001 in a nursery row of a nursery owned and operated by the inventor near Sanger in the San Joaquin Valley of Central California. The new variety was asexually reproduced, true to type, and retained all of the distinctive characteristics through asexual propagation generations. Asexual reproduction occurred by grafting on ‘Nemaguard’ rootstock (non-patented) in 2002 under the direction of the inventor near Reedley.

BRIEF SUMMARY OF THE INVENTION

The ‘GP10’ peach tree is characterized by producing a large, high-quality, semi-clingstone fruit that have very good external coloration and are mature for commercial harvesting and shipping around September 16-30 in a normal year in the San Joaquin Valley of Central California. The new peach variety is most similar to the seed parent ‘Prima Gattie’ (U.S. Plant Pat. No. 10,085) from which it is a seedling, and produces fruit 7-10 days later. The pollen parent of ‘GP10’ is unknown. The color of ‘GP10’ resembles the coloration of the parent ‘Prima Gattie’ with the red blush covering from 30-80% of the fruit surface. There is no pollination requirement for the claimed peach tree.
